Thanks in advance for your help, and I apologize for the 'bullet point style' message but I am a bit flustered. Brand new TAOTAO 150cc GY6 engine powered go kart. Tested oil levels prior to start up, they were near the upper level of the hash marks. During start up, exhaust smoked heavily. Assumed it was part of start up, let engine warm for ten minutes, still smoking, drove very slowly on paved neighborhood roads for one minute, still smoking from exhaust, then engine stalled when I let off gas during a slight downward slope. Pushed back home, and checked oil again, much lower (lower hash marks). Leaking visible when I get under scooter. Remove shroud, this gasket practically falls off. It looks like oil is coming from here. (Pictures below) So just a few questions, it that gasket just to keep the shroud from rubbing on the metal, or is it a badly installed valve cover gasket? If it is just a 'plastic on metal barrier gasket' should I just order a whole set of gaskets and start with the valve cover and see if that helps, because something is leaking, for sure. The main question I have is if I ruined my engine. Will fixing the leak (wherever it ends up being) and adding more oil allow the engine crank? I don't see how those things alone would allow the engine to start turning over if it is not turning over now (since that stuff is all just mechanical, right?), unless there is some safety that prevents start up based on low oil level? I am hoping this is the case, but I don't know enough about these engines to know what kind of protections they include. If I have ruined my engine, and fixing the leak and adding more oil will NOT help (maybe I have seized the engine?), what are my options then? Are there any resources for rebuilding an engine? I purchased from a dealer with a warranty, and am waiting to hear back from them, but I need to get all my ducks in a row to handle this on my own if they tell me to kick rocks. Thanks again for your help, and like I said, I am a bit flustered so I apologize if anything is coming out as gibberish or not explained well.

Being new I wouldn't dare touch it, I would wait till you hear from company sounds like a defect.

I would remove the valve cover make the gasket is in there.

Hi folks! Thanks for the replies! If I remove the valve cover, will engine oil spill out (or any other fluids?)

UPDATE: Decided to take the valve cover off as I was stuck with all other troubleshooting methods. Here is a pic of the gasket: imgur.com/vdSS3rYAnd a close up of the blemish: imgur.com/dSjygOxNew gasket is on the shopping list!

Thanks tvnacman, I found a local supplier an hour away I am meeting tomorrow for the part. Maybe next time!
I still don't know the reason it won't start, but at least this might solve the oil leak!

For the no start, I would pull the spark plug to see what it looks like. Then check for spark too.

Probably fouled the plug with all the oil that's getting by the rings,,,I would contact the seller/ dealer where you got it and explain what's going on,,,with no miles on it I'm sure they'll consider it a warranty issue

Cyborg, that may be what happened!
I also picked up a new spark plug, CDI, and ignition coil from the same dealer I got the gasket from.
Turns out the CDI had different terminal adapters, so I couldn't hook that up, but I was able to install the new spark plug and ignition coil, in addition to replacing the gasket.
Engine started up and was a bit rough, but after 10 minutes or so of gentle driving it was much smoother. There were a few times it shut off with moderate gas, so I would just let it sit for two or three minutes, start it up again, and try again.
Not sure if the bogging down with gas was due to the fact that it was still getting rid of everything from start up, or just because it was cold, but having gotten it started and running, I am much happier and will run more tests tomorrow.

I should have suggested checking the valve lash while you had the valve cover off.
How is the oil level? Blue smoke at first start up lasts a minute. If your still smoking (blue) then it's a ting problem like cyborg says. If it is more black it could be too rich and causing the boging.

No idea what valve lash is, but I will google it!
Oil level since changing the oil and replacing the gasket has held steady with no noticeable leaks!
Let the engine idle for five minutes before getting in this AM, has been working like a champ, no more smoke coming from the exhaust.

Thanks!
After a few more cold startups, it looks like in most cases it needs a gentle tap on the gas to start while pressing the ignition button, in addition to 5-10 minutes of idle time to really be in great running shape.
